[IDD #KZT-246763]: Fwd: LIGHTNING Feed for WIFIRE

Hi Mary,

Good to hear from you again!

Yes, I did the update.

re:

aeolus must be getting pretty "long in the tooth" ...

re:
> This morning I had a request from John Graham - about a feed for ldm.
> Could you please guide me as to how to properly allow the site requested
> access to lightning data:
> 
> # Larry Riddle address@hidden
> ALLOW   NLDN    ^aeolus\.ucsd\.edu$

Three things:

- the agreement with the providers of both sources of LIGHTNING data prohibit
  the re-distribution of the data beyond one's campus

  So, if the "site" in "site requested access" is something other than UCSD,
  you cannot add an ALLOW to relay the data.

  If the "site" is another department/group in UCSD, then you can relay the
  data if you already have it, BUT you need to remind the LDM/IDD administrator
  in that department/group that they are not allowed to re-distribute the
  data.

- there is already a blanket ALLOW for UCSD machines in place on aeolus:

#          UCSD machines
allow   ANY     ^[a-zA-Z].*\.ucsd\.edu$

  This ALLOW will work if the name of the REQUESTing ucsd.edu machine begins
  with an alphabetical character (i.e., it will not work if the machine
  name begins with a number, etc.).

- aeolus is not REQUESTing LIGHTNING data, so it will not be able to relay it

  But, there is already an ALLOW for LIGHTNING data on the source for the
  NLDN data, striker2.atmos.albany.edu.  So, if you add the following line
  to the ~ldm/etc/ldmd.conf file, aeolus will start receiving the data:

request LIGHTNING ".*" striker2.atmos.albany.edu

  And, if the ucsd.edu machine to which aeolus will relay LIGHTNING data 
  to has added an appropriate REQUEST to aeolus, LIGHTNING data will start
  flowing to it:

<in ~ldm/etc/ldmd.conf on the other ucsd.edu machine>
request LIGHTNING ".*" aeolus.ucsd.edu

Please let us know if the above helps!

Cheers,

Tom
